Sierra and Lima

These were the systems SDSC contributed to FutureGrid. Sierra comprised 84 compute nodes and two storage nodes. Each compute node had two sockets, each with a 4-core 2.5 GHz Xeon processor, for a total of 8 cores per node and 672 total cores for the system. Each node had 32 GB of DDR2 and was connected via 20-Gbps DDR InfiniBand interconnect. Sierra had a theoretical peak performance of 7 TFlop/s. It also had two Sun x4540 storage servers at 48 TB each for a total of 96 TB of raw storage.

Triton Resource

SDSC's precursor to the UCSD-RCI TSCC, Triton Resource had 256 general compute nodes, 28 high-memory nodes and a parallel file system. The general compute cluster had a peak theoretical throughput of approximately 20 teraflops and contained six terabytes of memory, while the high-memory cluster had a total peak throughput of nine teraflops and a total memory capacity of nine terabytes.

OnDemand Cluster

The OnDemand cluster was a Rocks cluster with Intel dual-socket, dual-core compute nodes. The 2.0 GHz, 4-way nodes have 8 GB of memory. OnDemand had a nominal theoretical peak performance of 2.4 TFlops.

An IBM terascale machine built in a configuration especially suitable for data intensive computations. It included 96 8-way P655+ nodes with 16 or 32 Gb of memory and 32-way P690 nodes with 128 or 256 Gb of memory. Peak performance - 15.6 teraflops

Retired Data Resources

A centralized file system for long- or short-term data storage of high-volume multi-site runs and large XSEDE-based data collections, GPFS-WAN was a 613-TB storage system mounted on several XSEDE compute resources.

Part of the SDSC Tape Storage platform, HPSS was a centralized, long-term data storage system for national users. With a 25 PB capacity, its content increased by over 100 TB a month while in production.

A high-performance archival storage system, SAM-QFS allowed users to directly access data using a disk cache file system, then automatically migrated the data to tape. For national users, it was part of the SDSC Tape Storage platform.
